I can't offer any expert advice on the behavior, but just a note; Whether a BEL has any gene-related problems depends entirely on what went into it. Lesser x Lesser creates a BEL that can be prone to bug-eyes, but obviously that would be visible. However, under that pretty white could be any number of genes that aren't visible. What you're describing doesn't sound like Spider-complex wobble to me, though, which is the only 'wobbling' behavior I'm personally familiar with. Honestly, it sounds more like some kind of airborne irritant, such as chemical fumes, just in my own inexperienced response to the description of her behavior.
